SPECIFICATION forming part of Letters Patent No. 733,824, dated `July 14, 1903.

Application led November l, 1902. Serial No. 129,762. (No model.)

granaries and also for taking grain from buildings where stored and loading same into wagons; and a further object of my invention is to produce an elevator of this kind which will be simple in construction and which may be operated by a small engine or by horse-power, as may be most convenient.

In the accompanying drawings, Figure l is a perspective view of myilnprovement, showing the elevator in operative position. Fig. 2 is a side elevation showing the device folded for transportation, parts of the wagon being broken away. Fig. 3 is a detail sectional view about onthe line 3 3 of Fig. 2.

In carrying out my improvement I employ a wagon-body A, with suitable running-gear, the wagon-body being of ordinary or any preferred construction. Ashaft B extends across the wagon-body, while to the rear is a shaft C, one end of which projects through the Wagon side and carries adjacent its outer end a ratchet C and a pawl C2 and at its end a crank-handle C3. Mounted on each side of the wagon-body are the standards D, connected at the top by the cross-rod D and braced by the pieces D- D3.

The elevator comprises two sections E and E', the first being the longer andthe second being adapted to rest on the first when the parts are folded.

The elevator E consists of the side and bottom pieces E2 E3, the conveyer E4, the strutbeams E5, and the brackets E6. The conveyer comprises the endless link chain E7 and the cleats E8. The short section E2 is similar in construction with the exception that the brackets and strut-beam are omitted, and similar parts in the two sections are designated Vby similar reference characters. Adjacent its forward or lower end the elevator E has the sides increased in height, as at E,

'G2 to the pulley G7.

for a purpose to be hereinafter described. The sides of the short elevator are also widened at its lower end, as at E10, to prevent grain from spreading and running over when it is thrown on the conveyer. To elevate the section E, drums'F are carried on the shaft C and pulleys F on the rod D', cables F2 passing from the drums over the pulleys and being secured to the sides of the elevator. By rotating the crank C3 the cables are wound on the drums and the elevator raised to the required inclination. Sprockets E11 are carried at each end of the elevators, the chains E5 Vpassing over them. To drive the conveyers, a pulley G is rigidly mounted 011 the shaft B. Smaller pulleys G G2 are mounted on the shaft adjacent one end. At the lower end of the elevator a pulley G3 is carried by the shaft G4, carrying the sprockets at thatend, and a belt G passes from the pulley G' to the pulley G3. A shaft G6 at the upper or rear end of section E carries a .pulley G1, while a belt Gs passes from the pulley The pulley G may be driven from a small gasolene-engine carried on the wagon, or it may be driven by horsepower, at the option of the user. Bars H are loosely mounted on the ends of the shafts B andGG, thus connecting the elevator E to the Wagon-body and lalso serving to hold the two shafts always at an equal distance apart and holding the belt G8 always taut. At its Vlower end brackets E12 are secured to the short section and carry rollers E13, the brackets and rollers serving to hold the end of sectionl and the conveyer from the ground. The

`side pieces E10 may be iared, if deemed desirable, as shown in Fig. 1.

The operation of the device, together with the mode of folding same, will be obvious from the foregoing. The upper partof the short section rests over the extension E9 when the parts are in operative position,a`nd the grain is thereby prevented from being blown over the sides E2 while falling from onecon- Veyer to the other. p

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a grain-elevator, the combination with a suitable wagon, sectional elevators of different lengths carried by said wagon, said IOO elevators comprising side and bottom pieces and having separate conveyers adapted to travel in them, the sides of said elevators being'increased in height at their forward ends, rthe rear end of the shorter elevator beingadapted to slide between the sides of the longer elevator7 the sides of the shorter elevator being outwardly flared at its forward end, and means for driving said conveyers.

2. In agrain-elevator, the combination with a sectional elevator, said sections comprising side and bottom pieces, the side pieces of the longer section being widened adjacent the lower end of the longer section, the rear end of the shorter section being adapted to slide between said widened portions and the sides of the shorter section being widened and outwardly flared at their lower ends, endless conveyers in said elevators, means for raising the sections and portable means for supporting them.

3. In combination with a wagon, a sectional elevator, means for raising the rear end of one section and lowering the forward end of the other section, an endless conveyer in each elevator, shafts at the end of each section, sprocket wheels on said shafts, sprocketohains connecting the Wheels of each section, a pulley mounted on the shaft at the rear of one section, a pulley on the shaft at the forward end of the other section, a shaft on the wagon, pulleys thereon, a belt running from one of said pulleys to the pulley at the rear of one section, a belt running from the other pulley to the pulley at the forward end of the other section, and bars pivotally secured to the wagon and adapted to hold the lastnamed belt taut.
